ing seeding arrangements disposed in staggered relation and with improved means for attaching to the drill proper andraising and lowering such staggered seeding arrangements. I i

A further object of the invention is to provide improved means for subjecting the staggered seeding arrangements to substantially equal yielding pressure stantially equal depth of seeding.

A further object of the invention is to provide a shaft mounted to be raised and lowered by manual means with arms extending obliquely thereacross and secured thereto with means for connecting the seeding arrangements resiliently to the extremities of such arms.

With these and other objects in View, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a view in rear elevation of a fragment of a drill embodying the present invention. Fig. 2 is a top plan view of a fragment of the drill embodying the present invention. Fig. 3 is a View of a drill in end elevation, the supporting wheel being removed, showing the relation of the 1 two gangs of disks.

Like characters represent corresponding parts throughout the several views.

The improved drill which forms the subject matter of this application comprises an axle 10, supporting wheels 11, and seed box or hopper 12 of substantially the usual and ordinary type.

At the rear of the hopper 12 a shaft 13 is journaled, preferably square, although not necessarily so, and carrying a plurality of arms, as shown at 14. While only one of the arms 14 is shown in the several figures Specification of Letters Patent.

of the drawing, it is to be understood that these arms are spaced along the length of the hopper and the shaft 13 as requirements and experience may dictate.

Pivoted upon the extremity of the arm 14- is-a shaft 15, which said shaft 15 is raised and lowered by rotating the shaft 13, such shaft 15 being carried as will be noted, upon the several arms 14: and raised therewith. A counterweight or spring 16 is provided to assist in the raising of the shaft 15 and arm 14:.

Spaced along the shaft 15 are a plurality of arms 17 rigidly secured to such shaft in any approved manner, as by forming the arms in sections, as shown more particularly at Figs. 2 and 3, and bolting such arms rigidly upon such shaft. It will be noted that the extremities of the arms 17 are staggered so that lines drawn perpendicularly through the shaft 15 and through the extremities of such arms will be substantially equally The extremities of the arms 17 are provided with slots 18 through which extend rods 19 which are in turn pivoted at their lower end, as at 20, to the shoes 21 carrying disks 22 for covering the seed passed through the shoes 21. The shoes and disks are further secured to the drill by means of links 23 pivoted as at 24.

Tension springs 25 embrace the rods 19 and hold the shoes and. disks to their work. Cotter pins or other securing means 26 are inserted through the upper extremities of the rods 19 and prevent such rods from passing outwardly through the slots 18.

By reason of the shaft 15 being journaled to rock it will be apparent that the gang of disks secured at'the rear of such shaft balance the gang of disks secured at the front of such shaft, so that the shaft will only rotate when all or a majority of the disks of one gang are given an upward or downward movement. As such movement is, however, only rare, it will be apparent that the arms will maintain substantially horizontal positions at all times irrespective of the position of the shaft 15, whether it be raised or lowered. When the shaft 15 stantially equal resilient pressure is put upon each and every disk of both gangs at all times and yet maintained in such a polique arms.

2. In a drill, a part adapted to be manually raised and lowered, a shaft journaled upon the raising and lowering part, arms extending rigidly and obliquely across the shaft and provided at their extremities with openings, rods extending downwardly through the openings and provided with springs and seeding devices carried upon the lower end of the rods.

3. In a drill, a part adapted to be manually' raised and lowered, a shaft journaled upon the raising and lowering part, arms extending obliquely across and rigidly secured to the shaft and provided with extremities having'openings therein, said open extremities coinciding substantially with equally spaced parallel lines perpendicular to the shaft, seeding two rows, and rods connecting sald devlces to the shaft and seeding devices carried upon the extremities of such arms. 4. In a drill, a part adapted to be manually raised and lowered,'a shaft journaled in said part, arms extending across and rig idly secured to the shaft and having their outer ends coinciding substantially with equally spaced parallel lines perpendicular devices arranged in with the ends of the arms. s

5. In a drill, a support adapted tobe manually raised and lowered, a rocking shaft journaled in such support, arms secured to and projecting forwardand rearward from the shaftytheouter ends of one set of arms standing opposite the spaces between the outer ends of the other set, seeding devices arranged in two rows and in staggered relation to each other, swing ng supports for the members in said rows, and individual connecting means between the front members andfront arms and the rear members and rear arms respectively.
